Description
Color & Appearance: Deep chocolate brown, espresso, charcoal black to dark gray background, often enriched with subtle bronze or olive undertones. The surface is highlighted by a complex, interwoven network of golden-yellow, amber, and white veins that radiate dynamically, resembling lightning strikes or constellations. This striking pattern gives the stone a “galaxy” or “spiderweb” visual character, making each slab unique and highly decorative.
Texture & Structure: Fine- to medium-grained crystalline structure with a compact formation. Smooth surface with natural depth; polished finishes enhance contrast and highlight the intricate veining.
Pattern: Irregular, flowing, and interconnected veining with strong movement. No repetition; each slab features a distinct natural composition.
Physical & Mechanical Properties:
- Apparent Density: ~2.68–2.72 g/cm³
- Water Absorption: 0.20–0.40%
- Compressive Strength: 105–135 MPa
- Flexural Strength: 10–15 MPa
- Mohs Hardness: 3–4
Chemical Composition (% by weight):
- CaCO₃ (Calcium Carbonate): 90–95%
- MgCO₃ (Magnesium Carbonate): 1–4%
- SiO₂ (Silica): 1–3%
- Fe₂O₃ (Iron Oxide): 0.3–0.8%
- Other Trace Elements: <1%
Mineral Composition (% by weight):
- Calcite: 80–90%
- Dolomite: 3–6%
- Quartz: 1–3%
- Mica / Iron-bearing minerals: 2–5%
Usage: Ideal for luxury interior applications such as feature walls, flooring, countertops, bathroom vanities, fireplaces, columns, and decorative architectural elements. Its bold veining makes it especially suitable for statement pieces and book-matched installations.
Maintenance: Requires sealing to enhance stain resistance. Clean with pH-neutral cleaners and avoid acidic substances to prevent etching. Periodic polishing is recommended to maintain surface gloss and highlight veining contrast.
Note: Due to its strong natural variation and dramatic veining, slab selection is recommended for projects requiring visual consistency or book-matching.
